FLASH-LIGHT GS-BURNER.

SPECIFICATION forming part of Letters Patent No. 695,014, dated March11, 1902.

Application filed November 14, 1901. Serial No. 82,316. (No model.)

To al whom it #my concern:

Beit known that I, DELL WARD, a citizen of the United States, residingat Grand Rapids, in the county of Kent and State of Michigan, haveinvented a new and useful Flash- Light Gas-Burner, of which thefollowing is a specitication'.

My invention is an improved automaticallyoperating flash-lightgas-burner especially adapted for illuminating glass signs and foranalogous uses; and it'consist-s in the peculiar construction andcombination of devices hereinafter fully set forth and claimed.

In the accompanying drawings, Figure l is a sectional view of anautomatically-operating Hash-light gas-burner constructed in accordancewith my invention. Fig. 2 is a similar view showing a modification.

' In carrying out my invention I employ an expansible gas-holder l, which may be of any suitable construction and is here shown as comprisinga Water-seal chamber 2 and a vertically-movable bell 3, the lower sideof which is disposed in said Water-seal chamber. A gas-pipe 4, whichextends upwardly in the gas-holder from the bottom thereof, is adaptedto supply gas to the gas-holder from any suitable source.

The bell 3 or vertically-movable member of the gas-holder is here shownas provided with a burner 5, which communicates with an opening 6 in theupper end of the bell. A valve 7 is provided, which in coaction with thesaid opening regulates the escape of gas from the gas holder. The valveis here shown as hinged at one end under the top of the movable elementof the gas-holder, as at 8, and as being disposed to cover the opening6, as shown in Fig. l. A guide 9 depends from the upper side of the bellor movable element of the gas-holder and limits the movernent of thesaid valve. In the form of my invention shown in Fig. l the valve 7 isprovided with an orifice l0 of slight diameter to constantly supply thetip of the burner with a small quantity of gas,so that a small iiame maybe kept constantly burning for the` purpose of igniting the largervolumes of gas consumed intermittently by the operation of the burner inthe production of the dash-lights. An

operating-rod 11 is connected to and depends lower portion of the rod 11operates in a guide 2, which projects from one side of the gassupplypipe 4,' and the lower end of said rod l1 is bent to form a trip-arm 13,which, in c0- actionwith said guide l2, which also forms a stop byarresting the ascent of the rod ll near the limit of the upstroke of thebell or movable element of the gas-holder, causes said rod to open thevalve 7, and thereby permit the gas accumulated in the gas-holder to befed to the burner 5 and burned brilliantly, creating a iiashing lightwhich endures during the descent of the bell or movable element of thegas-holder.

It will beunderstood that the pressure 0f the gas under the bell ormovable element of the gas-holder will keep the valve 7 closed and causethe said bell to rise until the trip 13 of the rod ll by engaging theguide and stop 12 opens said valve, as hereinbefore de scribed. As thegas is being supplied to the burner during the downstroke of the bellthe pressure thereof on the valve is diminished and the Weight of thevalve, together withthat of its operating-rodll, keeps the valve openduring the descent of the bell and While Vthe flashing light is burning.

In the modiiied form of myinvention shown in Fig. 2 the gas-pipe 4 isprovided with a by-pass, here shown as a pipe 14 of diminished diameter,which leads to an igniting constantly-burning burner 15, disposed insuch relation to the burner 5 as to ignite the gas, which escapes fromthe latter intermittently by the automatic operation of my improvedburner.

I do not desire to limit myself to the precise construction andcombination of devices herein shown and described, as it is evident thatmodiiications may be made therein without departing from the spirit ofmy invention.

IOC

In practice I provide the seal-chamber With vertical guides 16, whichproject from the upper end thereof, and provide the upper end of thebell 3 with a stop, here shown as a transversely-disposed bar 17, theends of which operate in said guides. Said guides and stop limit theascent of the bell.

Having thus described my invention, I claiml. Anintermittently-actinggasburnercomprising a gas-holder having an elementmovable in one direction by the pressure of the gas therein, saidmovable element having a gas-escape passage, a valve, carried by saidmovable element, to close said gas-escape passage and maintained inclosed position by the pressure of the gas during the outstroke of saidmovable element, and a connection between said valve and a xed point toopen said valve at the limit of the outstroke of said movable element,substantially as described.

2. In a gas-burner of the class described, the combination of anexpansible gas-holder having means to supply gas thereto, the movableelement of said holder having a gas-escape passage, a valve pivotallyconnected to and carried by said movable element and actuated by thepressure of the gas to close said passage during the outstroke of saidelem ent, and means to open said vvalve at the limit of the outstroke ofsaid movable element, substantially as described.

3. In a gas-burner of the class described, the combination of anexpansible gas-holder, having an element movable in one direction by thepressure of the gas therein, said movable element having a gas-escapepassage, a valve to open and close said passage, said valve beingmovable with said movable element and maintained in closed position bythe pressure of the gas during the outstroke of said movable element,and means to open said valve at the limit of the outstroke of saidmovable element and close said valve at the limit of the reverse strokeof said movable element, substantially as described.

4. In a gas-burner of the class described, the combination of aneXpansible gas-holder, having an element movable in one direction by thepressure of gas therein, said movable element having a gas-escapepassage and a burner to Which said passage leads, a valve to open andclose said passage and maintained by the pressure of the gas in a closedposition during the outstroke of said movable element, said valve havinga gas-passage of reduced capacity therein, and' means to close saidvalve at the limit of the instroke of said movable element,substantially as described.

5. In a gas-burner of the class described, the combination of anexpansible gas-holder, having an element movable in one direction by thepressure of gas therein, said movable element having a gas-escapepassage, a valve, carried by said movable element, to open and closesaid gas-escape passage, an operating element connected to said valveand having a trip and xed stops, alternately engaged by said trip, toopen and close said valve at the limits of the strokes of said movableelement, substantially as described.

In testimony that I claim the foregoing as my own I have hereto afxed mysignature in the presence of two Witnesses.

DELL VARD.
